Foreskin gets cracks after sex. Sometimes it goes for few days and comes back again after intercourse. Seeing whitish Grey discharge building on foreskin and on penis head. It goes after washing but comes back next day again. It seems skin around the head looks getting some infection. I have tried applying coconut oil and curd also after reading some online articles for possible fungus/yeast infection. My wife had some uti infection & white discharge. what may be the reason and treatment.
